Development and commercialization of therapeutics involving new and emerging technologies present the market with new challenges, from establishing secure supply chains of critical raw materials to creation of customized solutions. At Thermo Fisher Scientific, we rise to this challenge by applying our breadth and depth of technologies and resources to support your efforts. Let us help select the right products for your applications.
Accelerated development of mRNA-based therapeutics has necessitated the transformation of standard, research-grade in vitro transcription (IVT) reagents into raw materials specifically designed and manufactured under advanced quality standards (Table 1). TheraPure reagents for mRNA therapeutics provide our partners access to the most experienced development, analytical, and manufacturing teams in the industry.

The TheraPure enzymes for in vitro transcription are manufactured under stringent animal-free and ampicillin-free processes. These enzymes are grown in media and purified completely without animal-sourced components. Our AOF manufacturing process eliminates potential prion (bovine spongiform encephalopathy and transmissible spongiform encephalopathy) and virus-derived disease risks. Components of animal origin are replaced with AOF components throughout the manufacturing process—from fermentation to enzyme formulation.
The absence of animal-derived materials in the manufacturing process minimizes the need for excessive traceability documentation and accountability. In addition, the AOF enzymes help to reduce the risk of ampicillin-related allergic reactions and other side effects.
Generation of mRNA by in vitro transcription includes several cleanup steps. Traditional purification techniques, like phenol:chloroform followed by precipitation or spin-column, have limited capacity with multiple steps and are not easily automated. On the other hand, magnetic bead-based technologies are flexible, scalable, and automation friendly. An mRNA purification protocol based on Invitrogen Dynabeads MyOne Carboxylic acid and a proprietary binding buffer can deliver higher yield than traditional purification methods.
